Fiat Panda Key Fob Replacement

fiat 500 key cutting Panda key fobs contain an transponder chip that transmits an alert to your car to open the doors and start the engine. The fob can stop functioning due to a variety reasons.

cropped-KeyLab-1.pngThe most commonly cited reason for key fob malfunction is an inoperable coin battery. Other reasons include water damage, malfunctioning receiver modules and signal interference.

Dead Coin Battery

If your key fob's battery has gone out of service, the first thing to do is replace it. Make use of a new button battery with identical in size, voltage and specifications as the previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) It must be cleaned before being used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can work wonders.

If the key fob has not been exposed to water but still does not work, there may be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan can help in these instances.

Water Damage

If your key fob's battery has taken a bath in the pool or puddle or walked to the washing machine, you might have some water damage. It's possible to repair it by taking the batteries off and cleaning the circuit board using ruby alcohol. It's a good idea to let the fob dry completely before putting in a new battery.

You may have a faulty module if your key fob stops working after replacing the battery or updating. You can find instructions for reprograming the majority of remote keys on YouTube or in your owner's manual. You can also reset the computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob contains the chip that communicates the vehicle's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. Dropping the key fob could result in this, as can water exposure. If the key fob stopped working after water exposure it may be possible to fix the issue by cleaning the chip using isopropyl alcohol or electronic cleaner.

However, if the key fob still does not respond following cleaning, it is likely that the module is defective and will require to be replaced. A damaged receiver module may also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.

A defective electronic chip

The chip inside your key fob plays a vital part in the anti-theft security system of your vehicle. It sends a message to the immobiliser inside your car to inform it if the key is valid. Your car will not start when the chip is damaged.

A malfunctioning chip could be caused by interference signals from objects such as weather conditions, objects or transmitters on the same frequency in close proximity to your vehicle. In this situation you'll require an entirely new key fob.

Faulty Battery Contacts

The battery contacts on a key fob can be damaged by excessive usage. If they're broken or bent, the fob won't send any signals to the receiver modules in the car.

Modern fobs are equipped with rubber seals that keep out water. Submerging them in water, even if it's just the slightest splash or drizzle could damage the chip's electronic components.

The key fob contains a chip that communicates with the vehicle's immobilizer system in order to allow it to start. The system relies on cryptocoding systems in the latest vehicles or the red key system used in older ones. If the chip is damaged, it will need to be replaced.

The 12 Volt Battery is faulty

A defective battery can cause the key fob to function. The car's computer may not recognize the remote if this happens.

Test the battery with an voltmeter prior to replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops dramatically then it's time to replace it.

To test a battery's capacity test the battery's capacity by placing an electrical load on it for a couple of minutes. This will take away about 1 percent of the charge on the surface. Then, you can measure the voltage. The better the battery's capacity is, the longer it will maintain its voltage. The ideal is to keep it close to 12 volts during several minutes.

Problems with Radio Signal

This is the most typical reason for the key fob to stop sending signals to cars. This issue can be fixed by replacing the battery. However, it is important to choose a battery with the same voltage and size as the original one.

Fobs can take a lot abuse, and they aren't indestructible. The battery contacts and buttons could be damaged by rough handling.

A signal may also be interrupted by other transmitters or objects that use the same frequency. For instance, a light control panel in your home could transmit interference on the same bandwidth that key fobs use. This can affect the remote control of your car.

Afflicted OBDII scan tool

There are many reasons why scanners don't work. Some are more complex than others.

Professional scan tools enable mechanics to observe the car's network, and run various self-tests. These tools can help save time, but are expensive and out of reach for the majority of DIYers.

If your OBD2 scan tool won't power on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it's likely that a fuse has been blown. This is the most frequent reason for failure of the scan tool. The easiest fix is to replace the blown fuse.
